A gallon of milk cost $2.90 in 2002. In 2018, it cost
1 answer:
Answer:
<em>The cost of a gallon of milk changed 31%</em>
Step-by-step explanation:
<u>Percent Change</u>
Is the difference between two values of the same variable in different times or conditions, expressed as a percentage of the original value.
The formula is:
Where
v1 = original value
v2 = final value
The gallon of milk cost v1=$2.90 in 2002 and v2=$3.80 in 2018. The percent change is:
Pc = 31%
The cost of a gallon of milk changed 31%

Answer:
The points that verify the system of inequalities are:
point E, pointF, and point G.
Step-by-step explanation:
Please see the attached image that illustrates the boundary lines in your system of inequalities.
The boundary line for the inequality is depicted in green, while the boundary line for the inequality
is depicted in red.
By solving for y in each inequality, we understand which half-plane should be considered for the inequality:
First inequality (green boundary line) :
This means that we are to consider the points below the green boundary line.
Second inequality (red boundary line) :
This means we have to consider the points below the red boundary line.
Recall as well that both conditions we arrived at have to be satisfied by the points that are solutions of both inequalities.
From the image, we can see that there are only three points that reside at the same time below the green and the red boundary lines. These points are: point E, pointF, and point G.
On the other hand, we have two points that lie on a boundary line (point J and H), but they should be ignored, since the system of inequalities contain just inequality symbols < or >, and not the "equal" sign.
